Problems solved by technology

Although many efforts have been made to develop optical reproducing players adopting the BD specifications, there are many difficulties in developing a complete optical reproducing player since the BD specifications have not been fully established yet.
However, in the present Blu-ray Disc (BD) standards, because consolidated standards of the supplementary data, particularly the menu information are not complete yet, there are many restrictions on the development of a Blu-ray Disc (BD) optical reproducing apparatus, which causes problems with reproducing the menu information and providing it to the user according to a request of the user.

Abstract

In the data structure for managing reproduction of graphic information, first graphic information is stored multiplexed with main data in a first clip file and second graphic information is stored in a second clip file separate from the first clip file.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of the Korean Application No. 10-2003-0097528 filed on Dec. 26, 2003 which is hereby incorporated by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to high density recording media such as read-only blu-ray discs (BD-ROM) and methods and apparatuses associated therewith. [0004] 2. Discussion of Related Art [0005] Generally, an optical disk on which a large capacity of data is recordable is widely used as an optical record medium. Recently, many efforts have been made to develop a new high density optical record medium (HD-DVD) on which video data of high definition and audio data of high quality can be recorded and stored, such as a blu-ray disk (hereinafter abbreviated BD) and the like. [0006] The blu-ray disk (BD) as a next generation HD-DVD technology is the next generation optical record solution enabling storage of data ...
